    In this study, we introduce research aimed at developing a compact particle-excitation flow control valve that enables continuous control of air flow rate. We have been developing a compact control valve with continuous flow control for application to soft actuators. The control valve that we are developing uses particles as a valve plug, which does not require a valve plug positioning function and allows the control valve to be miniaturized. Furthermore, by controlling the movements of the particles on the orifice, the control flow rate can be made finer and the response can be improved. On the other hand, the past driving principle used the resonant mode of an oscillator utilizing a piezoelectric element (PZT) to control the motion of the particles. In this vibration mode, the size of the oscillator limits the miniaturization. Therefore, we propose a drive method that uses simple plate deflection vibration mode. This drive method eliminates the need for a large oscillator, and thus reduces the size of the control valve. To confirm the feasibility of the proposed drive method, we fabricated a prototype and evaluated its characteristics during flow control.

    This paper proposes a drive principle that aims to improve the control characteristics of a particle-excitation flow control valve capable of continuous air flow control. Aiming at application to a small servo valve, the authors have developed a particle-excitation flow control valve that controls flow rate by separating particles, which act as a valve element, from an orifice that is opened by the oscillation of a piezoelectric element. This paper proposes a method of more finely adjusting the motion of the particles. This method makes it possible to adjust to what degree each orifice opens, thereby refining the control of the flow rate and improving the responsiveness of the valve. Here, the authors produce a prototype, evaluate its characteristics, and confirm its effectiveness.

    This paper describes an improved particle-excitation flow-control valve with high flow rate and controllability. The proposed control valve has a small volume, is lightweight, and can smoothly control the airflow through particle excitation. Pneumatic actuators, which have many advantages, are widely used in automation machine equipment and are expected to be used in robots. In general, such highly controllable pneumatic-control devices used as proportional valves are large-scale, heavy, and exhibit low response. We have developed a new flow-control valve called a particle-excitation flow-control valve, which has a simple structure with a lead zirconium titanate (PZT) resonance mode, large control-flow rate, and is lightweight. Further, this valve is expected to be highly responsive because it is driven by a PZT vibrator. In this study, we designed an experimental prototype to increase the maximum flow rate and measured its flow control and response characteristics. Moreover, we showed that this control valve has high controllability and control flow rate.

    The authors have previously developed a compact, light-weight air flow control valve, which realizes continuous flow control. The vibration produced by a piezoelectric device (PZT) was used to excite particles confined in a flow channel to control the valve opening for the developed control valve. Therefore, the voltage applied to the PZT can be changed to continuously control the flow rate. A new working principle was developed for the control valve to stabilize flow rate characteristics. Different types of particles were used to change the valve opening condition. A prototype was manufactured to demonstrate the effectiveness of the control valve.

    The purpose of this study is the development of a valve that can precisely control pneumatic cylinders. The valve is lightweight and has simple structure. The valve uses a piezoelectric oscillator which is driven in the resonance mode, and it can control flow rate by controlling the amplitude of the particle excitation. In this report, we have designed a new prototype for the purpose of high controllability. We have applied a non-linear control algorithm to control Q-V nonlinearlity of this valve. We found that this control works well to realize linear Q-V characteristics.

    <p>Diamond cutting tools shows severe wear in turning of steels. In previous paper, it was shown that carbides on ferrite phase, which were precipitated by carburization, suppressed the diamond tool wear. In this paper, detailed distribution of constituents of the carbides was analyzed by EDS (energy-dispersive X-ray spectroscopy). In addition, characteristics of each carbide such as occupancy, diameter, and degree of circularity were measured. Results indicate that those characteristics of the carbides influence suppression of the tool wear.</p>

    Recently, demands have increased on fabricating complex and accurate structures by ultra-precision cutting. However, the machinability is influenced by crystallographic orientations in micron/submicron cutting. In our past work, it was clear that the crystal anisotropy affected the elastic recovery in submicron groove cutting of single crystal copper. Before the experiments, three-step cutting, i.e., rough cutting, intermediate cutting, and finish cutting, have been employed to flattening single crystal copper surface. The depth of affected layer was thinned by increasing the number of intermediate and finish cutting. Nevertheless, few microns of affected layer remained on finished surface. The rough cutting step is considered to cause the remaining affected layer. In this paper, we have investigated the effect of cutting conditions of the rough cutting step to reduce the depth of affected layer. The Schmidt factor of each slip system was calculated from measured cutting forces. Results suggest that the slip system and its Schmidt factor may explain the machinability, and results indicate that the thickness of affected layer decrease with an increase in cutting speed.

  • Development of removal amount estimation method based on calculation of elastic deformation of superabrasive stones during multistage superfinishing of sapphire Reviewed

    In planarization processes of sapphire, lapping process takes a long time because sapphire is a hard material. In contrast, superfinishing, which involves fixed abrasive machining, can substitute for lapping, and it would be possible to shorten the amount of processing time. In this work, vitrified-bonded diamond superabrasive stones with different grain diameters are developed. Then, multistage superfinishing is investigated by combining these stones. Results indicate that the multistage process is capable of producing a 2 nmRa surface, equivalent of a lapped surface in less than 10 min. To improve the process of multistage superfinishing, a removal amount estimation method is developed based on the real contact pressure calculation. The working area ratio of the stone was calculated by considering elastic deformation during superfinishing. The contact ratio of sapphire is calculated considering the roughness of the pre-finished surface and grain depth of cut. Accordingly, the real contact pressure is calculated to estimate the removal amount during superfinishing and finished surface roughness was expected.

    Our goal is the development of a design system for mechanochemical superabrasive stones containing both cBN and CeO<sub>2</sub> abrasives. As the first step, we have already developed a morphological structure model for the stone using fractal modeling techniques. As the second step, this paper describes the surface topography model for the stone. We have already proposed a surface topography model for the stone containing only cBN grains. This model can describe the surface topography with the same fractal dimension of grain distribution as the morphological structure model. Therefore, we have improved the model by preparation of the describing parameters for each grain and the changes in these parameters through the describing algorithm. As a result, the model bears resemblance to the real stone in topography and fractal dimension in each grain of the topography model is approximately equal to the morphological structure model.

    A pneumatic actuating system has many advantages, including great power, small weight, safe use, and low cost. Air control devices are needed to control pneumatic actuators. However, the control devices that provide high controllability, such as proportional valves, are heavy and large scale; therefore, a smaller and lighter control valve is desirable. We previously proposed a valve mechanism using particle excitation by a piezoelectric (PZT) vibrator that boasts the advantages of small size, small weight, and continuous airflow control. In this report, we designed prototype using bolt-clamped Langevin-type transducer (BLT). And the parameters are optimised that orifice position, particle condition, and orifice size for proportional, stable flow condition.
